Painting Wall Panelling in London: Georgian Dados to Contemporary Shiplap

Painting Wall Panelling in London: The Complete Guide

Wall panelling has never been more popular in London interiors. From the authentic Georgian dado panels of a Belgravia townhouse to the contemporary shiplap installed in a newly converted Shoreditch warehouse, panelling adds architectural interest, texture, and a sense of quality that painted flat plaster walls cannot match.

But panelling is also one of the most demanding interior painting tasks. The combination of flat panels, raised or recessed mouldings, corner joints, and long horizontal or vertical lines means that preparation and application technique matter enormously. A poorly painted panelled room looks worse than no panelling at all — every brush stroke in the wrong direction, every paint run, every filled joint is amplified by the three-dimensional surface.

This guide covers the main types of panelling you will encounter in London homes, the preparation and paint systems appropriate for each, and the common mistakes that lead to disappointing results.

Types of Panelling in London Homes

Georgian Dado Panels

The dado panel — a lower section of wall divided into individual framed panels below a chair rail or dado rail — is one of the defining features of Georgian and Regency interior architecture. In London, you will find authentic Georgian dado panelling in properties dating from the early eighteenth century through to the 1840s: the houses of Mayfair, St James's, Bloomsbury, and Belgravia all feature this style of panelling in their original reception rooms.

Authentic Georgian panelling is solid timber — typically pine or deal for secondary rooms, oak or mahogany for principal rooms — constructed in a traditional frame-and-panel system. The raised or fielded panel (where the panel face is bevelled back from a raised central field) is characteristic of the Georgian period. These panels were designed to be painted, and the historic paint finishes on original Georgian panelling were oil-based, producing a hard, slightly translucent surface that is very different from modern emulsion.

Original Georgian panelling in London properties often has accumulated dozens of paint layers over two centuries. The temptation to strip back to bare timber and start again is understandable, but in practice paint stripping of in situ panelling is an enormous task and risks damaging the timber. In most cases, careful preparation of the existing painted surface — filling, sanding, priming where necessary — is preferable to complete stripping.

Victorian Tongue-and-Groove

Tongue-and-groove matchboard panelling was widely used in Victorian properties for service areas, bathrooms, kitchens, hallways, and stairways. Applied in vertical boards with a V-groove between each board (creating the characteristic ribbed pattern), it is a practical and robust wall treatment that has since become fashionable far beyond its original service-area origins.

Victorian tongue-and-groove is typically softwood — deal or pine — and is normally painted rather than varnished. The joint between each board is the critical point: if the paint does not fully penetrate the V-groove, moisture can enter and cause the boards to swell, eventually splitting the paint film along each joint line.

Victorian Bolection Mouldings and Raised Panels

Above dado level, many Victorian reception rooms feature full-height panelling with more elaborate moulding profiles. The bolection moulding — a profiled moulding that projects proud of both the frame and the panel — is particularly characteristic of later Victorian work. These larger-scale panelled rooms require a more theatrical approach to colour and finish, as the moulding profiles catch the light and need to be painted with care to maintain their crispness.

Contemporary Shiplap and Featherboard

Shiplap panelling — horizontal boards with a rebated joint between each board, creating a shadow line — has become extremely popular in London homes over the past decade. Installed as a complete wall treatment, a partial height dado treatment, or a full panelled feature wall, contemporary shiplap is almost always MDF or moisture-resistant MDF rather than solid timber.

Featherboard (also known as clapboard), which uses tapered boards fixed horizontally, provides a similar effect with a more pronounced shadow line and a slightly more rustic feel. Both shiplap and featherboard are typically found in contemporary interiors, kitchen-dining rooms, bathrooms, and garden rooms.

MDF Panelling

Fully profiled MDF panelling — supplied as panels with routed grooves to simulate traditional frame-and-panel construction — has become the most common form of newly installed panelling in London homes. It is available in a huge range of profiles and grid patterns, from simple Georgian-style grids to more elaborate Baroque-inspired designs. MDF panelling is an ideal substrate for painting when properly prepared.

Preparation: The Critical Stage

Whatever type of panelling you are painting, preparation is where the quality of the final result is determined. No amount of careful application technique will rescue a poorly prepared surface.

Filling and Levelling

Nail holes and fixing heads must be filled flush with the face of the board or moulding. Use a flexible, paintable filler. On MDF, the face veneer can dent easily; use a fine surface filler and apply slightly proud of the surface before sanding back flat.

Joints and gaps are the most common problem area. On newly installed panelling, some movement and shrinkage is inevitable in the first heating season, and joints that were tight when first painted may open slightly over time. Fill joints with a flexible acrylic caulk rather than a rigid filler — rigid fillers crack as the panelling moves.

Between panelling and plaster — the junction between the top of a dado panel and the wall above — is particularly prone to cracking. A neat bead of flexible caulk at this joint, smoothed flush, will prevent the crack from reappearing after painting.

MDF end grains must be sealed. The cut edge of MDF is highly absorbent and will absorb paint at a different rate from the face, producing a noticeably different sheen level unless sealed with an appropriate primer (shellac-based primer or high-solids acrylic primer applied to all cut edges before finishing).

Priming

New MDF panels must receive a full primer coat before any finishing paint is applied. Unprimed MDF will absorb paint unevenly, and no amount of topcoats will compensate. We typically use either a water-based high-build primer or a solvent-based primer depending on the finish coats to follow.

For previously painted timber panelling, spot-prime any bare timber or filler before applying a full coat of appropriate primer to the entire panelled surface.

Paint Selection: Oil vs Eggshell vs Satinwood

Traditional Oil-Based Eggshell

For authentic period panelling — Georgian dado panels, Victorian bolection moulding rooms — traditional oil-based eggshell remains the gold standard. It cures to a hard, durable surface with excellent flow and levelling properties, producing a smooth, glassy finish without visible brush marks when applied correctly. The depth of finish on oil-based eggshell cannot be quite matched by water-based alternatives.

The disadvantages are well known: slow drying (24 hours between coats), strong odour (requiring excellent ventilation), and a tendency to yellow over time, particularly in rooms with limited natural light or where gas appliances are in use.

Best for: Original Georgian and Victorian panelling in period rooms where an authentic finish is the priority.

Water-Based Eggshell and Satinwood

Modern water-based eggshell formulations have improved dramatically and are now a genuinely competitive alternative to oil-based products. Brands like Farrow & Ball's Modern Eggshell, Little Greene's Intelligent Eggshell, and Zinsser's AllCoat produce excellent results on both timber and MDF. They dry faster, have lower odour, and do not yellow.

The sheen level of water-based eggshell is typically slightly higher than oil-based, and the finish feels slightly less deep. On MDF panelling, water-based eggshell is usually the better choice: MDF does not benefit from the additional flexibility of oil products in the way that solid timber does.

Best for: MDF panelling, contemporary shiplap and featherboard, period rooms where odour or drying time is a concern.

Dead Flat and Soft Sheen

For contemporary shiplap installed in a living room or bedroom, some clients prefer a flat or near-flat finish that reduces the visibility of the shadow lines between boards. Farrow & Ball's Estate Emulsion applied to panelling can look beautiful in the right room — the flat, chalky surface has a quality that suits both the texture of the boarding and many heritage paint colours. The downside is durability: flat emulsion is easily marked and harder to clean than eggshell.

Colour Choices for Panelled Rooms

The colour of panelling dramatically affects the character of a room. There are no universal rules, but several principles are worth considering.

All-over panelling in a single colour (including walls above the dado) creates the most dramatic, immersive effect. Dark panelled rooms — in deep greens, navy blues, or charcoal — are particularly fashionable and work well in dining rooms, libraries, and home offices where a sense of enclosure is desirable.

Contrasting dado and upper wall is the traditional approach for dado panelling: the lower panelled section in a deeper, more durable shade; the upper wall in a lighter, coordinating colour. The dado rail provides the visual break. This approach works well in hallways and staircases where a more practical finish at lower level makes sense.

White or near-white panelling against a coloured wall creates a crisp, architectural effect that suits Georgian panelling particularly well. The contrast draws attention to the quality of the moulding profiles.

Application Technique

Painting panelled surfaces correctly requires a clear sequence and careful brush technique.

Work from the inside out. For frame-and-panel construction, paint the panels themselves first, then the horizontal rails (top and bottom), then the vertical stiles. This order ensures that any wet paint overlapped at junctions is absorbed into the outer elements, minimising visible lap marks.

Lay off carefully. The final brush strokes on each element should run in the same direction — typically vertical on stiles and panels, horizontal on rails — and be applied with a lightly loaded brush using long, even strokes. This is what creates the smooth, even finish that distinguishes professional from amateur work.

Don't overload the brush. Excess paint collects in the internal angles of mouldings and runs. Keep the brush lightly loaded and remove any build-up of paint in corners immediately with a dry brush.

Common Mistakes

Painting over unprimed MDF. The single most common cause of a poor result on new MDF panelling. Always prime thoroughly.

Using emulsion on woodwork. Standard emulsion is not designed for woodwork and will not hold up to the abrasion of normal use. Always use an appropriate eggshell, satinwood, or gloss product.

Painting joints without caulking. Joints between panels, and between panelling and adjacent surfaces, will crack if painted without first being filled with flexible caulk.

Applying paint too thickly. Thick coats of paint run, sag, and dry with an uneven surface. Two or three thin, well-sanded coats will always produce a better result than one thick coat.

Forgetting to sand between coats. A light sand with 240-grit paper between each coat produces a noticeably smoother final surface. Skip it and the finish will never be quite as smooth as it could be.
